Q1Domain Verified
In the context of a Rankine cycle, what is the primary thermodynamic limitation that prevents achieving 100% efficiency, even with ideal components?
The energy losses associated with pump work in compressing the working flui
D) The heat transfer limitations within the boiler and condenser.
The temperature difference between the heat source and the heat sink, as dictated by the Carnot efficiency.
The inherent irreversibility of the turbine expansion process.
Q2Domain Verified
For a supercritical boiler in a power plant, what is the principal advantage of operating above the critical point of water?
It eliminates the need for a separate economizer and superheater, simplifying boiler design.
It minimizes the risk of thermal stress and fatigue in boiler tubes due to phase change.
It allows for higher steam temperatures, leading to significantly improved thermal efficiency.
It reduces the required boiler pressure, thereby decreasing capital costs.
Q3Domain Verified
In a reheat Rankine cycle, the steam exiting the high-pressure (HP) turbine is sent back to the boiler for reheating. What is the primary purpose of this reheating process?
To recover some of the heat lost in the condenser, thereby improving thermal efficiency.
To decrease the specific volume of the steam, allowing for smaller LP turbine designs.
To reduce the moisture content of the steam exiting the LP turbine, thereby preventing erosion of turbine blades.
To increase the overall work output by increasing the enthalpy of the steam before entering the low-pressure (LP) turbine.
